In Ge July 15, 1937 I 1 Claim. (c1; 229-23) Round boxes have beenknownfor a long time. They are supplied by the manufacturing industriesgummed or pressed complete. On account of the manufacturing costs andshipping ex- 5 pensesbeing considerably elevated, these beauti-. fulboxes were not so successful as the straight edge folding boxes.

Experiments of various kinds have been made to manufacture collapsibleround boxes, which failed however, as the mounting of the boxes requiredtoo much work and involved greater consumption of materials, and formany other difllculties.

. It is known to make a collapsible roller-like 15 cardboard box, inwhich the openings of the closed cardboard roller areclosed withcap-like covers.

It is also known to make a non-gummed cardboard box in such a mannerthat by the aid of die moulds the individual parts are lined with inthin paper and thereby kept together.

The two mentioned, boxes are of a somewhat similar type, but as regardsthe principles and 35 stitching and without the use-,of machines, tools,

etc. I

Fig. 1 shows the bottom of the box formed by the two disks I and 2. Thedotted line 3 represents the outside gumming line.,

"Fig. 2 shows the cross-section of the bottom and in which way the twodisks are pasted; In particular here the-ungummed rim and the slotlikegroove become visible. 45 Fig. 3 shows the rim of the bottom part of thebox. The flaps I and I which are bent rectangulai'ly inwardly at thescore lines 6 in setting the box together. The flaps only serve fordecorative purposes. The closing of the rim consists of slot If and theflap 8.

Fig. 4' shows the lid 'of the boxwhich only distinguishes itself-fromFig. 1 by a somewhat \larger diameter. Y I V Fig. 5 shows the rim ofthe'lid which only distinguishes itself from Fig. 3 by an extendedlength according to Fig. 4.

such a way that the rims are lying unglued on the rims.

In order to describe the invention more clearly, reference is made tothe annexed drawing showing a box of 'circular shape with loose coverass in Figs. 6 and '7, in which v No. i is a plate forming the basepart, to which 5 a smaller plate 2 is gummed, stitched or attachedin'any other way in such a manner that the gummed surface, or fasteningline begins at or on line 3 (Figs. 1 and 2) in inward direction.Thereby, a free, slot-like grooved rim 2-3. is 1 formed which isdesigned to receive the teeth of the belt. The exact length of the beltpart is determined by the circumference of plate 2. The lengthwise sidesof the belt (Fig. 1i) of the base part are provided with round teeth 4,5 which serve, partly for jointing the double bottom, partly forstiffening and decorative purposes (as visible, see Fig. 6). The scorelines 6, H enable the teeth to be folded over easily and precisely.

The parts of the top (Figs. 4'and 5) are distinguished from those of thebottom part only in two-respects: 'the belt of the upper part andtherefore also plate 9must be of longer or larger form as they willlater have to fit over the. belt of the bottom part. The belt of the toppart is I provided with teeth only on one side, Fig. 5.

when mounting the box, the teeth of the belt are bent rectangularly ininward direction and set into the groove of the corresponding plates ofthe upper or lower part, respectively. When closdesign. Figs. 6. and 7showthe round folding box mounted complete in opened condition.

By giving the double plates diflerent forms it is possible to produce agreat variety of box shapes. r

The invention cannot only be used in connectionwith thick paper andcardboard, but is also suitable formetallic and modern raw materials.

Having nowv described my invention I declare that I claim as new:

A round foldingbox consisting of bottom, cover, and two flattened outrims which, when required, can be set up by the user to form a two-partbox without glue or other additional means thus characterized that thebottom and cover consist of two cardboard disks which are glued togetherin top of each other ina certaindepth forming a slot-like groove whichrectangularly bent rimflaps are inserted and, in closing the rims,connect the bottom and the cover respectively firmly with HANS PABB'I.
